How Much Should You Feed a Leopard Gecko? A Simple (Real-Life) Guide
Looking for a clear answer to “how much should I feed my leopard gecko?” You are not alone. Most advice online is either too vague (“feed a few insects”) or too strict. This page keeps it simple: use the calculator above to get a solid starting point, then adjust gradually based on weight trends and tail condition.
Quick answer (no fluff)
A good feeding amount depends on three things: weight, age, and body condition. Younger geckos usually eat more often. Adults usually do better with fewer meals per week. The Feeding Quantity Calculator estimates a reasonable range of feeders per meal, then gives you a simple weekly plan you can actually follow.
Why “just give 6 crickets” is not enough
“6 crickets” means nothing without context. A 30 gram juvenile and a 70 gram adult should not get the same meal. Feeder types also vary: dubia roaches are usually heavier per insect than crickets, and waxworms are much richer. That is why the calculator asks for feeder type and size, not just a random number.
What the calculator is really doing
The tool estimates a meal size based on a percentage of body weight, then converts that into an approximate insect count using typical feeder weights. It is not “perfect science,” but it is consistent, repeatable, and good enough for real-world decisions.
Step-by-step: how to use this Feeding Quantity Calculator
- Weigh your gecko in grams using a kitchen scale.
- Enter age in months (estimate if needed).
- Select body condition based on tail thickness.
- Pick feeder type and size (be consistent for a few weeks).
- Tap Calculate and follow the per-meal recommendation for 2 to 3 weeks.
- Adjust slowly by 1 to 2 insects per meal if weight trends are moving the wrong way.
Feeding frequency by age (simple guideline)
- Hatchlings and juveniles: more frequent meals, smaller feeders.
- Subadults: start spacing meals out, focus on steady condition.
- Adults: fewer meals per week is often better than huge meals.
If you want weight gain or weight loss
For gentle weight gain
- Add 1 to 2 insects per meal or add 1 extra meal per week.
- Do not change both at the same time.
- Weigh weekly to confirm progress.
For gentle weight loss
- Remove 1 to 2 insects per meal or reduce meals per week.
- Keep treats rare (especially waxworms).
- Track weekly weight and tail thickness.
Common mistakes (and how to avoid them)
- Changing too much at once: adjust one thing at a time.
- Ignoring heat and setup: appetite and digestion depend heavily on proper temperature.
- Too many rich treats: waxworms are fun, but not a daily plan.
- No tracking: weigh weekly and watch tail condition for real feedback.
Quick summary
- Feeding quantity depends on weight, age, and body condition.
- Adults often do better with fewer meals per week.
- Switching feeder types changes the number. That is normal.
- Adjust slowly and track weekly weight trends.
FAQ
How many dubia roaches should I feed my leopard gecko?
It depends on weight, age, and roach size. Use the calculator above, select dubia roaches and the correct size, and follow the per-meal range. Then track weekly weight and adjust slowly.
Should I feed my adult leopard gecko every day?
Many adults do better with 2 to 4 meals per week. Daily feeding can lead to gradual weight gain unless portions are very small.
My gecko will only eat mealworms. Is that okay?
Mealworms can work, but many owners prefer rotating feeders for variety. If mealworms are your main feeder, keep portions consistent and track body condition closely.
Why is my leopard gecko not eating the recommended amount?
Appetite can change with temperature, stress, shedding, and season. Double-check heat, try smaller feeders, and reduce stress at feeding time. If refusal continues with weight loss, contact an experienced reptile vet.
How often should I weigh my leopard gecko?
Weekly weigh-ins are a practical baseline. Use the same scale, same day, and similar time for consistent tracking.
